I think you're crazy. But that OK, I like crazy.
I've never heard of the expression, but we have a lot of expressions in our family that mean absolutely nothing to most people.
For example, to change the topic, we say, "Speaking of Christmas..." One summer, back in the 70's, my friend was watching Hawaii 5-0 with her dad, mom, and sisters, when her dad came out with that phrase. Since the episode wasn't about Chrismas, and no one was talking about Christmas, it stuck, and now my family uses it too.
We also use, "You're a mean drunk Superman" a lot. I'm sure you've heard the joke about the two guys drinking in a bar on the top of a skyscraper. One guy bets the other that the wind currents are so strong up there that a person could jump out the window, and the currents would bring him back to the window. The second guy takes the bet, so the first guy jumps out the window, and a few seconds later pops back in. The second guy says, I have to try that, and jumps out. Of course the second guy lands on the pavement. The bartender looks at the first guy and says, "You're a mean drunk, SUperman."
